Help With OBD Code P1237

Peace,

Please help. I loaned my other OBD device to a fellow mini driver. The service engine soon light came on after some jerking motions. The code reads P1237. Thanks.

Secondary upstream manifold air pressure sensor low input. Check connections on your map sensor to make sure it's not loose. You might have to get your map sensors replaced
